Using case pattern analysis, this study examines Catholic male workforce trends in the majority Catholic countries of Chile, Ireland, and Poland. Employing denominational data for three categories of church male professionals in the 1950–2010 time period, I document four important trends. First, ordinations to the diocesan priesthood in Ireland went into decline especially after Vatican II, have been relatively stable in Chile with only a moderate increase in the 1990s, and spiked in Poland in the 1980s, 20 years after Vatican II. Second, in all three countries the average defection rate among diocesan seminarians increased in the 2000s compared with the earlier two decades. Third, the religious priest workforce has declined in Chile, has been relatively stable in Ireland until the 2000s, and is growing in Poland. Fourth, from the late 1960s there has been a decline in the workforce of religious brothers in each country, especially in Ireland. The theoretical contribution to the Catholic workforce literature is discussed in terms of a critical events argument emphasizing the impact of Vatican II, prophetic stances, sexual scandals, and papal visits on labor market trends. I conclude with implications for the study of religion and society in general.
